Available in PDF, EPUB and Kindle. Book excerpt: Optical Interference Filters Using MATLAB® provides a foundation for the development of MATLAB code for simulating the performance of thin-film optical structures that can be combined to make interference filters. MATLAB has excellent calculation and visualization capabilities that together are well aligned to the matrix methods commonly used for thin-film calculations. The simulations developed in this book begin with filters based on simple dielectric materials both with and without dispersion. Building on the discussion of these simple filters, simulations are next developed for metal-layer-based induced-transmission filters, and finally for complete thin-film interference filters. Readers ranging from students to practicing scientists and engineers will find that these simulations work well in conjunction with other textbooks in the field, or they can stand alone. The ability to generate custom programs and tune them to explore specific features of optical interference filters is anticipated to enhance the designer's understanding and appreciation of the subtleties involved in filter design.

Download or read book Design and Development of Optical Thin Film Interference Filters for Visible Region written by Amit L. Sharma and published by . This book was released on 2022-09-12 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical Thin film coating technology is one of the oldest and continuous growing technology. Innovations in thin film coating technology are allowing scientists and researchers to design new types of optical filters for various applications. These thin films find wide spread use in various fields such as electronics, sensors, biomedical, laser instrumentation, new screen display technologies, smarter windows, protective coatings for glass and polymer substrates, head up displays, helmet mounted displays, see through displays, projection displays and efficient photovoltaic devices. In addition, these films find applications in optical industries for manufacturing of filters such as band pass, band stop, edge filters, notch filters, high reflection filter, anti-reflection filters, beam splitter, neutral density filters, etc. Such films work on the principle of interference of light to achieve desired optical characteristics such as reflection and transmission. Apart from the optical properties of the film such as reflection and transmission, there are various other parameters which plays major role in achieving desired quality of films. These parameters include film thickness, surface quality, average roughness and the tilt in deposited film. Depending on the wavelength and region of interest in the electromagnetic spectrum, the materials could be selected based on their optical transparency, density and refractive index. The commonly used materials for the deposition of thin films include dielectric metal oxides, metals, fluorides and composites. In the present research work, dielectric oxides such as silicon dioxide, Aluminium dioxide, titanium dioxide, tantalum dioxide, zirconium dioxide etc. were used for the visible region of wavelength. Although, these materials are commonly used for the deposition and fabrication of optical thin films but still the requirement of desired optical performance has made the role of manufacturer quite challenging. So, there is a need to achieve high accuracy and wavelength selectivity with minimum optical thickness, reduced side harmonics outside the stop band, lower bandwidth and low total cost of the coating process. The present study is based on minimization of side-lobes using various methods such as conventional quarter wave Ostack, AR coating on both sides of the conventional stack, classical rugate, matching layers along with quintic and Gaussian apodization functions applied on both sides of the rugate structure. Conventional and graded index techniques were used for designing of various optical interference filters such as antireflection, high reflective band stop filters (single, double, triple), band pass cavity and notch filters for the application of see through displays in the visible region. The optical thickness of all the designs was less than 10 μm with 1.3 to 2.5 variation in refractive index. The performance of all the designs in terms of peak reflectance or transmittance and side-lobe suppression were studied and compared. Few of the designed filters were fabricated using the electron beam deposition and dual ebeam Ion assisted deposition on BK7 glass substrates for normal incidence angles. For the realization of multilayer filter, determination of the optical performance of the single layer and tooling factor is important for excellent repeatability and reproducibility. Hence, single layer films of silicon dioxide and aluminium dioxide were deposited at normal. In addition to understand the change in refractive index of the coated film at different angles the single layers were also deposited at oblique angle of incidence ranging from 10 to 80°. Further, with obtained indices from the single layer, the conventional multilayer stack and inhomogeneous stack reflective filters were deposited at normal incidence angle at a central wavelength of 550 and 610 nm for application of see through displays and projection systems.
Download or read book High Spectral Density Optical Communication Technologies written by Masataka Nakazawa and published by Springer Science & Business Media. This book was released on 2010-08-12 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growth of Internet traf?c in recent years surpassed the prediction of one decade ago. Data stream in individual countries already reached terabit/s level. To cope with the petabit class demands of traf?c in coming years the communication engineers are required to go beyond the incremental improvement of today’s technology. A most promising breakthrough would be the introduction of modulation f- mats enabling higher spectral ef?ciency than that of binary on–off keying scheme, virtually the global standard of ?ber-optic communication systems. In wireless communication systems, techniques of high spectral density modulation have been well developed, but the required techniques in optical frequency domain are much more complicated because of the heavier ?uctuation levels. Therefore the past trials of coherent optical modulation/detection schemes were not successful. However, the addition of high-speed digital signal processing technology is the fundam- tal difference between now and two decades ago, when trials of optical coherent communication systems were investigated very seriously. This approach of digital coherent technology has attracted keen interest among communication specialists, as indicated by the rapid increase in the pioneering presentations at the post-deadline sessions of major international conferences. For example, 32 terabit/s transmission in a ?ber experiment based on this technology was reported in post-deadline session of Optical Fiber Communication Conference (OFC) 2009. The advancement of the digital coherent technologies will inevitably affect the network architecture in terms of the network resource management for the new generation photonic networks, rather than will simply provide with huge transmission capacity.
